摘要:

实验研究红茶菌液对鲜切马铃薯褐变的影响。在贮藏过程中对鲜切马铃薯的硬度、L*值、VC含量和多酚氧化酶活力变化进行测定。结果表明:红茶菌液能明显抑制鲜切马铃薯多酚氧化酶活力,能明显保持鲜切马铃薯VC含量,对保持鲜切马铃薯硬度有一定作用,对鲜切马铃薯L*值影响不大。初步证实了红茶菌液对鲜切马铃薯具有防褐变效果,且其效应因子是由红茶汤液经红茶菌发酵后带来的。

关键词: 鲜切, 马铃薯, 红茶菌, 褐变

Abstract:

The effects of tea fungus on polyphenol oxidase activity, L* value, vitamin C content and issue hardness during the ripening process of fresh-cut potato stored at 4 ℃ for 5 days were investigated. The results indicated that the tea fungus could significantly inhibit the polyphenol oxidase activity of potato, and positively keep the content of vitamin C and issue hardness of potato, but has little effects on the L*-value. In conclusion, tea fungus can prevent the browning of fresh-cut potato, which may be due to the fermentation of black tea soup by tea fungus.

Key words: fresh-cut, potato, tea fungus, browning
